Completed a Master Bath renovation in April 2020.  Working with JAR accomplished just what we had hoped, a seamless, smooth, clean renovation.  Most appreciated the communication level provided by the owner and his selection of top notch, quality, responsible people he employees.  A shout out to Justin, our contact.  Although quite pricey in comparison to others we contacted, it was worth it to get the job we wanted done the way we wanted it done. - and all in the midst of a pandemic."

JAR Corp is the best!  We’ve worked with Jonathan’s team for over 20 years on many projects.  Always professional and courteous.  They deliver on all aspects of a project; high quality work, schedule, clean-up and close out.  I have recommended them to my friends many time over the years."

JAR Corp did a fantastic job renovating my 100 year old townhouse flat. This was a major renovation that entailed reconfiguring plumbing, substantial electrical work, and a kitchen gut and remodel. Details matter, and JAR Corp was very attentive to this. The quality of the materials used really shows, and I can't thank them enough for doing such a stellar job in a timely manner."

We cannot speak highly enough of JAR Corp. We are thrilled with our new bathroom and the way it was completed in November 2020, It is beyond our expectations. The project manager's attention to detail was outstanding and every person who entered our home was respectful and tidy. The job was completed with expert craftsmanship in all trades. Every night the worksite was immaculately cleaned up. We highly recommend JAR Corp and look forward to having them remodel a second bathroom."

After years of managing several properties in Chicago, and having negative experiences with other vendors, I can say officially that JAR Corp is the best of the best!  We have completed several projects this year at both our home in the city and in the burbs. Top quality talent, done in a timely fashion (even dealing with all the new parameters around Covid), plus honest and accurate pricing - as they say "you get what you pay for" and JAR is worth every penny!

When we meet unexpected challenges (as does often happen in construction!) JAR navigates these quickly, effectively, and with minimal disruption to our predetermined timelines. 

We are so grateful for this working relationship and look forward to many more projects down the line!"

JAR Corp has done several jobs for me and I have always been impressed with their quality of work.  The owner is very responsive and the crew are respectful and efficient.  I highly recommend JAR Corp for your home repair needs."

While we were out of town Jar Corp took care of our house. When we had extrordinary snow storms Jar was there to shovel our flat roof and relieved us of our concerns. Jar Corp is always responsive and we cannot think of anyone else that we would rely upon."

We called in JAR for problems with Ice Dams this winter.  They responded immediately and quickly assessed the cause.  They made a recommendation, gave a detailed quote and did the work beautifully.  Their people were prompt, courteous and left the house clean.  They arrived on time as well.  I highly recommend them anytime."

As always with JAR Corp, excellent work. Our radiator valve leaked and it meant we needed to replace the valve but also gain access to it. The solution was to replace the radiator grills. Emily found us much less expensive grills than the ones we were originally going to purchase. So, on top of getting the job done with the always talented Jose (our Foreman), she found us less costly alternative grills to purchase."

We have worked with JAR Corp for years on many house projects.  This past year they helped us on everything from replacing our front doors to installing a new water, to doing interior and exterior painting.  They are a general contractor and can also do ground up construction.

Jonathan and his team are professional and amazingly responsive.  We would of joy recommend them to anyone."

Jovanny did a nice job of painting the trim on our house and garage. He suggested good color changes. He suggestions saved us alot of money.

JAR Corp. managed and successfully executed a complete remodeling of a 3,600 sq.ft. apartment I had purchased in the Chicago Gold Coast.  Every detail was completed to my satisfaction.  The team JAR assembled for my project could not have been more responsive.  All of this happened during a very difficult time when Covid was stressing everyone out.  Notwithstanding many challenges the pandemic posed, JAR completed the project in a timely fashion.  It seemed to me that the JAR team approached each task in the overall project as real artisans who very much cared about the quality of the work they produced.  It showed in the painstaking detail evident in every element of the renovation.  I could not have been more pleased."

Dan M.

They are the best! Very responsive and capable."

Cindy

The repair on our downspout collector box took only a phone conversation, a few emails and voila all was organized and repaired with  aesthetically pleasing results."

I've been using JAR Corp for almost 20 years - They are always professional and do excellent work.  When I have painted a room myself (NOT something I plan to do again!) it's embarrassing the contrast.  Their work is meticulous yet done efficiently."

Terry N.

Jar Corp. has done a lot of work for us over the  years.  They always stand behind their work. They are first class."

HU

JAR has done renovation in our home from basement to the second floor. We have scheduled the work done at our time frame and it all seems top be working out. The work is excellent and the fellows Danny and Jose are there to assist."

BD

JAR is the most phenomenal contractor we have worked with in 14 years of living on the north shore.  When Jonathan commits to a project, he follows through until done with Emily making sure there are no gaps in the schedule.  Work is beautiful, employees are courteous beyond words, and their follow up is beyond compare.   Completely recommend!

Who ever reads this should b so lucky to get Jar to work with them. My project started in 2022, while I was at my other residence. They did everything they said they would & did it beautifully. I thought they were easy to work with, always had time for me.



I would use them again in a second.:

Maribeth B.

This was our first project with Jar and it was a wonderful experience. Over the course of months, we had many of their employees and contractors working in our home. Each and every one was courteous, professional and a pleasure to have in the house! Their work was impeccable from start to finish and their attention to detail was amazing. We highly recommend Jar and look forward to working with them again in the future!

Everyone we've interacted with at JAR has been nothing short of professional, transparent and helpful. Project updates, expectations and timelines are expressed clearly."
